rlhis invention relates toknew anduseful improvements in wrenches` One objecty ot the invention `is toprovide a wrench which is simple in construction, and which can be manufactured at a low cost. 1 'f n s. K Another object is to provide a wrench wvliich is formed from few parts, and which is strong and durable in operation.

A further object is `to provide a wrench wherein the stationary jaw of the pipe engaging portion is formed for use in drawing nails and tacks. A.

Other objects and advantages jwill be apparent from the following description when taken in connection with the accompanying drawing. i Y In the drawing:

Figure 1 is an elevation of a wrench made in accordance with the invention. Y

Figure 2 is an endjview looking toward the outer` orstationary jaw to show the nail and tack extracting claws thereof.

kFigure 3 is an edge view of the `wrench looking inwardly toward the pipe jaws.

Figure '4l is a vertical sectional view through the movable jaw on the line 4 4 of Figure 3, showing'V the manner in which the movable j aw :t'ace is mounted and the means for turning the jaw movingscrew bar.

Referring particularly to the accompany ing drawing, the shank of the wrench isformed from a single length of round bar metal doubled at its intermediate point to produce the longitudinall parallel -leg portions 10 which have their outer extremities stationarily secured within openings 11 in the stationary jaw 12 of the wrench. The intermediate portions of the legs 10 of the shank, are oiiset inwardly, as shown at 13,

and the portions beyond such offset portions extending in parallel relation but slightly closer together than the portions at the other side of the offsets, said closer portions being connected by the bightportion 14, and yform the hand grip of the wrench. The movable jaw consists ota block 15 having the three openings 16 and 17, formed vertically therethrough, the openings 16 receiving the legs 10 slidably therethrough, while the other opening 17 is threaded. Extending between the portions 10, and above the oEsets-13,

with` openings receivingV thelegs 10,'therethrough, is a bar or plate 18. n

In one end of the block 15 there is formed a vertical vbituroation 19 inV which is disposed Athe stein 20 of the movable'jaw face of the pipe engagingportion'of lthe wrench. The lower tace of the head ofv thejaw tace is double beveled, as shown at21 and'22, respectively, the portion 21 being arranged to rest on the upper tace of the blockl, when the lface is engaged with a piece of work, and pressurey is exerted thereon, while the other face 22 engages with the upper face of the block, when pressure is relieved and the wrench is being turned for a new grip on the work.

Disposed` between the legs 10, and in pare Y y allel' relation thereto, is a threadedk bar or rod 23 the outer end being rotatably supported inv an opening 24 in the stationary jaw 12, which opening isV formed between the openings V1l. The other end of the threaded bar is disposed through thecenter 'tov of the plate 18, with its projecting endheaded, as at 23', to prevent longitudinal movement of the bar. Secured to or Vformed integrally with the threaded bar, inwardly Vof the platey 13, is an enlarged cylindrical,

and corrugated or scored member 25 which is grasped to rotate the bar. vThe bar 23 is threadedly engaged through the central threaded opening 17 wherebyk upon rotation of the bar the movable jaw or block 15 will be moved longitudinally on the bar and the legs 10, toward or away from the stationary jaw so that the portions l2 and 15 will grip a nut, orthe portions 12 and 15 grip a round piece of work, such as a pipe or round bar.

Particular attention is called tothe eX- treme simplicity of the wrench, and the fact that it is formed from the minimum num- Y ber of parts, thus rendering the same easy and oheapto manufacture. It will be noted that the bar from lwhich the legs 'l0 and hand grip portion are formed, is :formed from' a single length of metal, thus greatly ysimplifying the making of the wrench.

Furthermore, this bar serves to support both the stationary and movable jaws of the wrench, as well as the member 18 which supe ports one end of the' threaded bar. The said l length of bar metal provides the shank as `Well as the hand grip of the wrench.

lt is to be understood that various changes may be made Without the-slightest departure from the spirit of my invention;

lll/That is claimed is:

A Wrench ineludincDt-a*substantially U-r` shaped shank, a jaw member secured to the outer ends ot the legs of the shank, a blockslidable on the legs and forming a movable jaw, the legs being; offset inwardly intermediate their lengths7 a plate receiving' the legs therethrough and resting on the said offsets, and a threaded bar engaged through the movable jaw and having one end rotatably supported in the irst jaw and the other end rotatably supported in the plate between the said legs, said bar having a Cylindrical enlargement-ion; the last-named end between the movable jaw and the said plate and bear- 20 ing at all times against the plate.

In testimony whereof, I affix my signa-ture.
